  addr2line

  NAME

    addr2line - convert addresses into file names and line numbers.

  SYNOPSIS

    addr2line [-b bfdname|--target=bfdname]
              [-C|--demangle[=style]
              [-e filename|--exe=filename]
              [-f|--functions] [-s|--basename]
              [-H|--help] [-V|--version]
              [addr addr ...]

  DESCRIPTION

    The addr2line utility translates program addresses into file names and
    line numbers. Given an address and an executable, it uses the debugging
    information in the executable to figure out which file name and line
    number are associated with a given address.

    The executable to use is specified with the -e option. The default is the
    file a.out.

    The addr2line utility has two modes of operation.

    In the first, hexadecimal addresses are specified on the command line, and
    addr2line displays the file name and line number for each address.

    In the second, addr2line reads hexadecimal addresses from standard input,
    and prints the file name and line number for each address on standard
    output. In this mode, addr2line may be used in a pipe to convert
    dynamically chosen addresses.

    The format of the output is FILENAME:LINENO. The file name and line number
    for each address is printed on a separate line. If the -f option is used,
    then each FILENAME:LINENO line is preceded by a FUNCTIONNAME line which is
    the name of the function containing the address.

    If the file name or function name can not be determined, addr2line will
    print two question marks in their place. If the line number can not be
    determined, addr2line will print 0.

  OPTIONS

    The long and short forms of options, shown here as alternatives, are
    equivalent.
    -b bfdname
    --target=bfdname
        Specify that the object-code format for the object files is bfdname.
    -C
    --demangle[=style]
        Decode (demangle) low-level symbol names into user-level names.
        Besides removing any initial underscore prepended by the system, this
        makes C++ function names readable. Different compilers have different
        mangling styles. The optional demangling style argument can be used to
        choose an appropriate demangling style for your compiler.
    -e filename
    --exe=filename
        Specify the name of the executable for which addresses should be
        translated. The default file is a.out.
    -f
    --functions
        Display function names as well as file and line number information.
    -s
    --basenames
        Display only the base of each file name.
